If both assertion and reason are true but the reason is not the correct explanation of the assertion, then mark. 3. If assertion is true statement but reason is false, then mark. 4. If both assertion and reason are false statements then mark.
Assertion: \[N{{H}_{3}}\] is more soluble in \[CO\] than in plain water. Reason Carbonate is a weak base and reacts with the \[N{{H}_{3}}\] from the strong acid, causing the barium salt to dissociate.A) 1
B) 2
C) 3
D) 4
Correct Answer: A
Solution :
\[BaC{{O}_{3}}\]is more soluble in \[HN{{O}_{3}}\] than in water because carbonate is a weak base and react with \[{{H}^{+}}\] ion of \[HN{{O}_{3}}\] causing barium salt to dissociate. \[BaC{{O}_{3}}+2HN{{O}_{3}}\xrightarrow{{}}Ba{{(N{{O}_{3}})}_{2}}+C{{O}_{2}}+{{H}_{2}}O\]
